Pete Doherty has been asked to leave a rehab centre - because of his lack of commitment to giving up drugs.
The troubled British rocker was asked to cut short his one-month stay at The Cabin, a high-end drug rehabilitation centre in Thailand.
"At the end of the day - and this is actually quite common in the rehab institution - he basically worked out that he wasn't ready for recovery," explained marketing director Ben Moller.
He said Doherty, 33, had made progress during his three weeks at the £7,600-a-month recovery resort and his departure was amicable.
The exit from the centre had been the result of a "mutual decision", he insisted.
But he also said Doherty had been asked to leave because his lack of commitment might jeopardise the treatment of other patients.
Doherty, who fronted The Libertines and Babyshambles, has struggled for years with drug abuse, especially heroin.
He has visited Thailand before, taking a beach holiday in Phuket during the 2006-2007 New Year period with his then-girlfriend, supermodel Kate Moss.
He was also a friend of Amy Winehouse, who died last year of accidental alcohol poisoning.
Moller was asked if Doherty had been asked to leave because he had resumed taking drugs.
He replied: "He hadn't started using it, but that's what he wanted to do."
Moller said it was the nature of drug addiction recovery that one person's lack of commitment could affect others.
"To have even one person here out of 20 people or so that's not even motivated to be recovered or to achieve recovery, it's really disruptive for the other ones," he said.
"That's not because of Pete doing anything intentionally disruptive."
The Cabin is located outside the city of Chiang Mai in northern Thailand.
It has 27 teak cabins on a riverside site, and offers a modern, holistic programme with counselling and physical fitness.
Doherty's whereabouts after his discharge were not immediately known.
